The Fault in Our Stars - affectionately called TFiOS - film adaptation was released on June 6, 2014 and directed by Josh Boone.
It is an absolutely beautiful film! There is honestly no other way to describe it. It does the book justice and it is most definitely a book-to-movie an author can be proud of.

Character Opinions… Hazel Grace… Shailene, once again, has blown me away with her performance. I had practically forgotten that only a few months prior I had watched her portray Tris.
The chemistry between Shailene and Ansel was wonderful. It really captured the essence of the romance between Hazel and Augustus. It was so simple but absolutely beautiful!
Augustus Waters… Ansel was literally the life of the film. He portrayed Augustus so well! The humor was top notch and the slickness of his words were flawless. The pain that he displays is so raw and it hits you so hard that you honestly do not know what to do with it.
Isaac… Nat helped bring about the characteristics that made Isaac an empathetic character. Watching Nat portray this character made me super excited about the fact that he will be portray Q in my personal favorite John Green novel, Paper Towns. Side Note: The audience reaction to the physicality of Isaac and Monica in the beginning was hilarious - you’d think they didn’t read the book.
Peter Van Houten… I was not all that impressed with William Dafoe’s performance. I really didn’t hate Van Houten like I remember hating the character in the novel. I felt like this was a character that was just put in the movie because he is relatively important in the novel. I can’t place my finger on what exactly it was that the character was lacking, but he was lacking something.
Mr. & Mrs. Lancaster… I thought these two were well casted - especially Mrs. Lancaster. They were realistic enough yet optimistic which is what I would think would be needed in the situation these two characters are in.
Other Points… I was slightly confused at the beginning when it opened like one of the trailers. I thought it was a clever way to open it though.
I was quite pleased with the film and I recommend it. I also highly encourage that you read the novel, if you haven’t, before you go to see the film. It tends to help - just a thought.
